“the OP1 which is long and narrow (for me, it caused some hand cramps for my hands - 18.5 x 10.5)”
“Tried the OP1 8k. Was a bit narrow. Got the XM2 8k and it’s honestly my favorite mouse I’ve ever had”
“Never thought i would use a wired mouse ever again until i tried the op1 8k been using it as my main mouse for a few months and have no plan on switching anytime soon”
“I have tried a lot of mice, Nothing come close to the shape of the OP1. I would say its my endgame mouse.”
“The op1 was too narrow and forced me into a more aggressive grip that triggered hand and wrist pain quite fast.”
“This mouse is a god... Unfortunately, too small for me, so I ordered the xm2 8k ;)”
“I bought an Endgame Gear OP1 8k, but i wish I had gotten something similar to the superlight because the op1 is wayyyy too narrow.”
“The feeback of cable draging on the mousepad stiching and also the cable sometimes catching on my mousepad surface were bothering me a bit”
“This mouse is my endgame. Idk if it’s placebo but the 8k makes me feel like I can’t miss at all. Thanks for convincing me. This mouse is amazing so far!”
“I have a black op18k and the PF version and I prefer the coating and quality of the black one but I like the light clicks of the PF.”
“i have been using the op18k for about 10months on GX Speed mode and random clicks just started happening yesterday. clicks seem to register randomly when i rest my finger on left mouse button without pressing it. it felt like a switch durability issue.”
“i got an op1 8K, share the same experience as you, moved from a gpx to op1 8K and something just make me stay with it lol”
“The clicks feel amazing and the shape is really nice, but unfortunately it's a little too small for my hands and not very comfortable for a relaxed fingertip or claw grip.”
“This mouse is crazy. Forget the superlight and v3 pro”
“Yep, I had 2 op18k with teh cables breaking on me after 4 months of usage on each”
“OP18K in my case is a claw grip, but only the tip of my fingers control the mouse, feels very non-ergonomic, and I have a bit of a hard time swinging that cord around”
“I got used to it super fast, my aim just straight up improved, tracking, target switching just everything feels so much better with it. The shape is amazing for middle size hands claw gripping and fingertip it all just works. The latency is unmatched, the software is simple and just works. There is like nothing I can critique”
“Op18k is built for children. What a tiny fucking mouse lol. I bought it and gave it to a friend. I loved the build quality and it was incredibly well made and designed. Just absolutely tiny.”
“I really enjoy it overall but for some reason its the only mouse where I feel like I'm fighting myself to use it, whenever I glide it, it feels like im dragging my mouse”
“I bought this a week ago. I’ve got large hands. Hasn’t been an issue. Mouse feels great”
“I have OP1 8k v2 but after testing it went back to box. ATK F1 / Hitscan Hyperlight better mouse for me. That shape is best I have tested. Nothing special about OP1.”
“I really like the shape sadly I didn’t have the best experience with the build quality bc my copy developed a creak in the mb1 and it sometimes doesn’t hold the click”
“I've been using this mouse for four months and I love it. The firmware support on Discord is just so cool, they work better on their product than any other mouse manufacturer. The cable is fine if you know how handle it.”
“OP1 8k the cable stopped working and before the cable died, I was constantly getting double clicking, sensor issues and the shell being so creaky like a cheap toy.”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“I have the fastest latency mouse, the op18k, and can't differentiate it from any of my wireless mice (ulx, crazylight, f1 extreme, etc.).”
“My OP1 is from one of the first batches and it has quite a lot of wear, but despite that there is only a slight flex in the clicks and some fraying on the cable fabric.”
“when I got both my OP1 8k and XM2 8k I tested them in human bechmark against my Razer Viper V3 and was unable to really conclusively see a difference. I was getting about the same scores with all of them”
“Over an older mouse, absolutely. My previous mice were the aerox 3 and the basilisk pro (the first one) but over a different modern mouse, no not so much”
“From what I have seen so far, they are quite equal when you pre-pressure the op18k Button. But the light clicks of the superstrike feel imo just bettet”
“yeah I think the only tangible advantage is the click latency improvement, I did manage to set a personal record on reaction time benchmark with it”
“It makes a pretty big difference imo. Very noticeable when your games start to run and respond like shit because they don't support 8K polling.”
“when I go back to my op1 I feel like I have to be more intentional with my clicks. Not a bad thing, just something I noticed.”
“I found it made games lag at 8K, very bad in Fortnite for example. Even 4K was a bit suspect at times but overall fine.”
“Palm will be difficult, fingertip grip just fine. No issue with 18 cm, I was using it with 19 cm using claw grip.”
“I haven’t really played w 8k, mainly playing with 2/4k, but when i did try 8k it didn’t feel that different tbh”
“I had the issue where the left click wouldn’t respond but it got fixed when I turned off the slam filter.”
“I have both and honestly it feels about the same for me when using both op1 and x2 when playing cs2.”
“There is little to no difference when I compared against other top mouse clicks.”
